You are designing a networking infrastructure in multiple Oracle Cloud Infrastructure regions and require connectivity between workloads in each region. You have created a dynamic routing gateway (DRG) and a remote peering connection. However, your workloads are unable to communicate with each other.
What are two reasons for this? (Choose two.)
If workloads in different regions are unable to communicate, one possible reason is that the route table associated with subnets in each Virtual Cloud Network (VCN) does not have a route rule defined to forward the traffic to their respective Dynamic Routing Gateways (DRGs). This ensures that traffic is directed towards the remote peering connection. Another reason could be that the security lists associated with subnets in each VCN do not have the appropriate ingress rules to allow the traffic. Security lists control the flow of traffic at the subnet level, and if the necessary ingress rules are missing, communication between workloads will not occur.
